Kraken S40: The Macro Specialist ($359 USD)
40Ws power | 60° beam | 300-lumen spot light | 200g underwater | 1.2 sec recycle
Perfect For:
- TG-6/TG-7 macro shooters
- Dedicated macro photographers
- Budget-conscious beginners
- Travel minimalists
Real-World Performance
The S40 delivers plenty of power for close-up work. Shooting nudibranchs 6 inches away at f/8? You’ll have power to spare. The compact size makes it easy to position for creative lighting angles.
What it does well:
- Macro subjects at 6-12 inches: Excellent
- Lightweight and travel-friendly
- Affordable entry point
- Fast 1.2-second recycle time
- ~500 full-power flashes per charge
Limitations:
- Narrow 60° beam struggles with wide-angle shots
- 300-lumen spot light too weak for video
- You’ll outgrow it if you start shooting wide-angle
Macro Accessories
Snoot (optional): Push-on rubber boot design makes attachment quick and secure. Perfect for isolating tiny subjects with dramatic spot lighting.
Warming filter (optional): Reduces color temperature for more natural skin tones on fish and divers.
💡 Honest Assessment: The S40 works great if you’re 100% sure you’ll only shoot macro. But for $240 USD more, the S80 gives you 2x the power + a 3000-lumen video light. Most people who buy the S40 end up buying an S80 within a year anyway.
Kraken S80: The Versatile Workhorse ($599 USD)
80Ws power | 140° beam | 3000-lumen video light | 375g underwater | 1.0 sec recycle
Perfect For:
- Shooters who do both macro AND wide-angle
- TG-6/TG-7 users who shoot video
- RX100 photographers
- Photographers planning to upgrade cameras
Why the S80 is the Better Value
Here’s the math: S40 ($359 USD) + separate video light ($300 USD) = $659 USD. Or just buy the S80 ($599 USD) and get 2x the strobe power plus a 3000-lumen video light built-in. Easy decision.
What makes it special:
- Dual functionality: Strobe for stills, video light for clips
- Power to grow: Handles wide-angle shots, even with dome ports
- 140° beam: Covers wide scenes evenly
- Future-proof: Works great even if you upgrade to mirrorless later
- ~800 full-power flashes per charge
Macro Accessories
Snoot (optional): Bayonet mount design allows quick attachment/removal underwater. Essential for serious macro shooters who want precise lighting control on tiny subjects.
Warming filter (optional): Reduces color temperature for more natural-looking subjects.
Real-World Scenarios
| Scenario | S40 Performance | S80 Performance |
|---|---|---|
| Macro (nudibranch 6″ away) | ✅ Excellent | ✅ Excellent (power to spare) |
| Wide-angle (TG-6 w/ dome) | ⚠️ Struggles (60° beam too narrow) | ✅ Excellent (140° covers scene) |
| Video (4K clips) | ❌ 300 lumens too weak | ✅ 3000 lumens perfect |
| Night diving | ⚠️ Spot light only | ✅ Flood light illuminates path |
Specific Camera Recommendations
Olympus TG-6 / TG-7
For macro only: S40 works fine
For macro + wide-angle + video: Get the S80
The TG-6/7 can shoot excellent macro AND wide-angle (with wet lenses like AOI UWL-400). If you have any interest in wide-angle or video, the S80 is the smart choice.
Sony RX100 VII
Recommendation: S80
The RX100 shoots fantastic 4K video. Don’t cripple it with the S40’s weak 300-lumen spot light. Get the S80 and unlock the full potential of your camera.

Common Questions
Can I add a second strobe later?
Yes. Most compact camera shooters start with one strobe, then add a second within 6-12 months. Two strobes give you balanced lighting and eliminate harsh shadows.
Best practice: Buy matching strobes (two S40s or two S80s) for consistent color temperature.
Will these work with my wet lens (AOI, Weefine, etc.)?
Yes, but choose carefully:
- S40: Works with wet macro lenses fine, struggles with wide-angle wet lenses (beam too narrow)
- S80: Handles both macro and wide-angle wet lenses perfectly (140° beam coverage)
How long does the battery last?
S40: ~500 full-power flashes per charge
S80: ~800 full-power flashes per charge
In practice, you’ll get 4-6 dives per charge since you’re rarely at full power the whole time.
Do I need a snoot for macro?
For serious macro shooters: Yes. Snoots let you create dramatic spot lighting that isolates your subject against a dark background. Essential for nudibranchs, shrimp, and other tiny critters.
S40 snoot: Rubber boot design (push-on)
S80 snoot: Bayonet mount (quick-release)
Both available as optional accessories from Kraken.
Do I need a float arm?
For S40: Optional (it’s light enough at 200g underwater)
For S80: Recommended if you want neutral buoyancy
Kraken sells float collars for both models (~$30-40 USD).

Bottom Line: Which Should You Buy?
S40 makes sense if:
- You’re 100% committed to macro-only shooting
- Budget is absolutely maxed at ~$400 USD
- You’ll never shoot video or wide-angle
S80 is the better choice if:
- You want to try both macro and wide-angle
- You shoot any video underwater
- You might upgrade cameras in the future
- You want power to spare and not feel limited
Our honest recommendation: Unless you’re absolutely certain you’ll only ever shoot macro, get the S80. The extra $240 USD buys you versatility, future-proofing, and a legitimate video light. Most divers who “save money” with the S40 end up buying an S80 within a year anyway.
